Raised-dot slippage perception on fingerpad using active wheel device
نویسندگان
چکیده
To improve the slippage perceptual characteristics with the fingertip cutaneous sensation, we have introduced raised dots on the surface of a wheel rotating on an index fingerpad. Examining the perceptual characteristics of the raised-dot slippages by psychophysical experiments, we obtained factor effects on the perception. As a result of ANOVA, it was confirmed there was a significant difference among the three surfaces: the 3.2 mm period of raised dots, the 12.8 mm periods of raised dots, and the without-raised-dots smooth surface.

Effect of PbS Film Thickness on the Performance of Colloidal Quantum Dot Solar Cells
Colloidal quantum dots offer broad tuning of semiconductor band structure via the quantum size effect. In this paper, we present a detailed investigation on the influence of the thickness of colloidal lead sulfide (PbS) nanocrystals (active layer) to the photovoltaic performance of colloidal quantum dot solar cells. The PbS nanocrystals (QDs) were synthesized in a non-coordinating solvent, 1-oc...
متن کاملCompliant-linkage Kinematic Design for Multi-degree-of-freedom Mobile Robots
Multi-degree-of-freedom (MDOF) vehicles have many potential advantages over conventional (i.e., 2-DOF) vehicles. For example, MDOF vehicles can travel sideways and they can negotiate tight turns more easily. In addition, some MDOF designs provide better payload capability, better traction, and improved static and dynamic stability. However, MDOF vehicles with more than three degrees-of-freedom ...
متن کاملA comparison of tactile spatial sensitivity on the palm and fingerpad.
Studies of tactile spatial pattern perception have, for the most part, been carried out using the fingerpad. On the basis of these studies, models have been developed linking spatial pattern identification and resolution with underlying neural structures. It has been suggested that with appropriate scaling, these models would apply to the processing of spatial patterns presented to other sites ...
متن کاملComputation of Slip analysis to detect adhesion for protection of rail vehicle and derailment
Adhesion level for the proper running of rail wheelset on track has remained a significant problem for researchers in detecting slippage to avoid accidents. In this paper, the slippage of rail wheels has been observed applying forward and lateral motions to slip velocity and torsion motion. The longitudinal and lateral forces behavior is watched with respect to traction force to note correlatio...
متن کاملKinematic Bilateral Teleoperation of Wheeled Mobile Robots Subject to Longitudinal Slippage
With the widespread use of wheeled mobile robots (WMR) in various applications, new challenges have arisen in terms of designing its control system. One of such challenges is caused by wheel slippage. This paper proposes a new method for haptic teleoperation control of a WMR with longitudinal slippage (not including sliding). In this teleoperation system, the mobile robot’s linear velocity foll...
